摘要： A heat ray-shielding film has excellent heat-shielding performance and a color tone, and exhibits weather resistance. A heat ray-shielding laminated transparent base material and a heat ray-shielding resin sheet material use the heat ray-shielding film. The heat ray-shielding film and the heat ray-shielding resin sheet material are expressed by a general formula MyWOz, and contain a composite tungsten oxide particle having a hexagonal crystal structure, selected wavelength absorbing material, and thermoplastic resin. The selected wavelength absorbing material has a transmission profile in which a transmittance of a light of a wavelength of 420 nm can be set to 40% or less when a transmittance of a light of a wavelength of 550 nm is 90% or more, and a transmittance of a light of a wavelength of 460 nm is 90% or more.
